4 Claims.

This application comprises the same subject matter as in my former application, Serial No.

678,650,'filed July 1, 1933; and allowed'October This invention relates to the roofing industry and particularly to composition sheet roofing or strip shingles such as are now being extensively used. At present such roofing material is cut to shape and to certain standard sizes and designs in the factory, which necessitates the roofing con-'- tractor or retailer carrying a large stock of the different designs and colors to fit'all possible re quirements and this entails an outlay and tying up of a considerable amount of capital, with the probability of a certain percentage of leftover material and consequent waste.

The principal object of my invention is to avoid considerable of the expense of the present methods of merchandising such roofing by providing a machine to cut the shingle stock to the desired length and d ign from a plain roll of the material only as it is wanted; and which is-of such simple and inexpensive naturethat it can be bought by and installed in the'shop of a small roofing contractor at a relatively small expense.

Another object is to construct the machine so that it may be easily operated by one man and which requires no expense for operation or upkeep.

A further object is to arrange the machine so; that the pattern or design cutting die can be easily changed, so that the material may be cut to vari-' ous designs to suit individual purchasers without laying in a stock of material initially out to such designs as is now the case. The cost of the plain material in rolls being much less than that of the same area of factory-cut shingles, the contractor may make his customers a more favorable price than is at present possible and still net himself a profit, thereby of course tending to increase both the sale of the material and the volume of his business.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate correspondingparts in the several views:

Figure l is a side elevation of the machine as in operation.

Figure 2 is a top plan view of the same.

Figure 3 is' a fragmentary enlarged cross section on the line 3-3 of Fig. 1.

Figure 4 is a plan viewof the shingles formed by a single cutting operation of the machine.

Referring now more particularly to the char- (Cl; 164-20) I I acters of reference on the drawings, the machine comprises side frame beams I supporting a bed plate! or the like, the beams'in turn being supported a convenient height from the floor by legs 3. Cradles 4 forremovably supporting'the. spindles 5 of rolls of shingle material 6 to becut project forwardly "from and are mounted on said frame beams at their ends.

,Racks 'Iare mounted on and extend along the upper faces'of the side beams, said racks being engaged by gears 8 mounted on a common shaft 9' and having a' prfesser roller lIiconcentric therewith and extending'the full distance between the gears. The shaft is'journaled: at its ends in bearing blocks II mounted for limited vertical movem'ent in carriages I 1 depending outside the beams I. Said carriages have rollers I3 engaging the beams I so that said carriagesarefsupportedand guided for horizontal movement along the beams.

The bearing blocks are yleldably pulled down on the carriages by compression springs disposed about the lower portions of bolts'IS which are connected to said blocks at thesides and slidably dependthrough theacljacent portions of thecarriages, f I

Another geanli is mounted outwardlyof and concentric 'with' one gear 8,. which-gear I6 is engaged by a pinion I1 mounted on the adjacent carrlage in horizontal alinement with the gear. pinion is connected to a crank handle disposed, outwardly of said carriage so that upon rotationof the crank the carriages and roller III will be moved lengthwise of the racks and at the. same time the roller. willbe turned. L Secure'don the plate! c'e'ntrallybi its ends is a' rectangular die frame I9 in which'is mounted a die indicated generally at 20 andwhich indicates upstanding cutters 2i defining the pattern or design of the shingleto be cut from the sheet material of the rolls. The die parts are removably locked in the frame in a similar or the same manner as is employed in the printing industry in locking the matrices, etc., and the set-ups in their frames. The pattern cut by the die is preferably my own design, being arranged so that four single strips of standardwidth and length are cut at one time from the roll of material without there being any waste of such material.

The bearing blocks II are arranged in supporting relation to the roller III and to the level of the cutter so that when the blocks are at their I lowermost point of. the carriage the bottom of the roller Just clears the die cutter, as shown in Fig. 3 so that there is no possibility of said cutter being dulled by contact with the roller.
